Python: generate a different random choice when importing from module (different python file) - Keep getting same output

I have a code for choosing different comments from a list, which is stored in a separate python file, like comments.py:

import random

theitems = ['a','b','c','d','e','f']

commentpick = random.choice(theitems)

I have the following code in the main file:

from comments import commentpick

for a in commentboxes:
   a.send_keys(commentpick)
        

However the same comments will be returned for all the 'a' in commentboxes: [eg. 5 inputs, 'a', 'a', 'a', 'a', 'a']

It only works if i import random and do it on the main file, like this:

for a in commentboxes:
       a.send_keys(random.choice(theitems))

then the result will be varied, [eg. 'a', 'c', 'e', 'd', 'f']

Is there any way that I will be able to write a.send_keys(commentpick) directly without doing the random.choice in the main file but still get different results each time? Thanks.
